Abstract
A printing head for ink-jet printing comprises at least one ink-flow passage in the form of a hollow chamber and at least one ink-jet nozzle coupled to the ink-flow passage. The hollow chamber has a substantially uniform depth over substantially the entire area thereof. Preferably, the head comprises at least two laminated sheet-like members, one of the members having a hollow formed therein to comprise the ink-flow passage, and the other of the members having at least one nozzle formed therein. The head further comprises a flexible wall in communication with the hollowed chamber and a piezoelectric transducer connected to the flexible wall for producing ink-jetting pressure changes in the hollow chamber. Also disclosed are multi-nozzle printing heads with the chambers arranged in a circular configuration, and stacked double and triple decker arrangements.
